Now before anyone cuss me out, and or lock this thread, what program is best recommended to use to reverse enginner a psp program? I have one call Cain And Abel, but it dont work for me to use in my research. All it does is get passwords, etc. Prx Tool only output nids and command. I need the source code from the file. Thanks to anyone who help me.

As you said, prxtool. It will give you the ASM of an unencrypted prx. C or C++ code is up to your interpretation of the ASM.

if you mean a C decompiler, I didn't hear there is actually one for PSP.

IN my opinion, the cool part from reverse engineering is remaking the source code yourself by looking into ASM code.
It may be only me but that's what I think.
So, PRX tool.

I don't know of any decompiler for the allegrex as of yet, and I highly doubt there exists one, as it is a cumbersome thing to do. Lots of special cases and idioms that would have to be translated into high level language...
So your only choice is as A_Nub already stated. Use PRXTool and disassemble the executable and go at reversing the assembly to C manually.
And unless you are fluent in mips assembly, you can immediately forget about that and judging by your posts, that seems the case.

If you have what it takes to reverse engineer something you wouldn't be on a forum asking how to do it.
Reverse engineering requires dedication, hard work and LOTS AND LOTS of personal research. There is no magic recipe for it, every reverse engineering project is different, most breakthroughs in reverse engineering are made due to personal experience or just luck.
Usually you are reverse engineering something because people don't know what it does, if people don't know what it does it either means it's hard to figure out, people don't want to share or nobody cares. So really asking doesn't get you very far...

Also, we do not discuss game hacking here, it's completely off topic for this forum.
